Problems solved by technology

[0007] In order to solve the existing assembly and positioning process of the new traction rod seat, simple methods such as manual measurement, wire drawing, and marker pen marking can only be used. The operation process is time-consuming, labor-intensive, low in efficiency, poor in precision, and labor-intensive, so it cannot meet production needs; As well as to solve the technical problem that the new type of traction rod seat lacks a pair of positioning tooling for use with a laser marking instrument, the invention provides a symmetrical positioning device for a subway car traction rod seat

Abstract

The invention discloses a symmetrical positioning device for metro car traction rod seats, and belongs to the field of auxiliary positioning devices for rail car traction rod seat fitting up. The symmetrical positioning device comprises two width positioning mechanisms, two double-axis manual sliding tables, a middle line plane positioning mechanism and two lifting trolleys, and the width positioning mechanisms, the two double-axis manual sliding tables and the two lifting trolleys are sequentially and fixedly connected in the vertical direction in the one-to-one correspondence mode and jointly form two traction rod seat positioning mechanisms. Vertical baffles of the width positioning mechanisms of the positioning device and y-axis transverse jacking devices are used for positioning the horizontal posture of upper end plates of the traction rod seats, and base rotating discs and the double-axis manual sliding tables cooperate for usage and are used for slightly adjusting the rotatingangle of traction rod seat vertical plates and the positions of an x coordinate and a y coordinate; and the lifting trolleys are adjusted so that the interval and height of the traction rod seat positioning mechanisms can be determined.

Description

technical field [0001] The invention belongs to the field of auxiliary positioning devices for rail vehicle traction rod seat groups, and in particular relates to a symmetrical positioning device for a subway car traction rod seat. Background technique [0002] In the field of rail vehicle manufacturing, the forward direction of the car body is usually defined as the positive direction of the x-axis of the underframe, the direction in which the bolsters are arranged is defined as the y-direction of the underframe, and the vertical direction is defined as the z-axis direction of the underframe. [0003] A new type of subway car designed for the improvement of the Boston subway project in the United States. Due to the change of the bogie structure, a large-scale new double-column car body symmetrically arranged on the left and right along the xz vertical centerline plane of the car body is added under the underframe of the steel structure of the car body. The traction rod seat...
